Welcome back to another Foolish review of the coldest stocks, as ranked by Motley Fool CAPS. We're looking at the three worst-performing industries over the past 30 days, and your favorite short and long candidates in each.

Last time, and the time before, caching vendors were the lowlifes of the market's pity party. No longer. Their 20% loss over the past 30 days can't compare to the 27% drubbing that makers of baby gear have suffered over the same period.

And in third? Major carriers have left investors shaken up like a 737 in a thunderstorm. As a group, these low-altitude fliers are off 14.8% since late November.

According to you, our Foolish readers, the worst stocks in these industries to own now -- i.e., those rated one or two out of a maximum five stars in CAPS -- are:
